Description
TECHNICAL FIELD
The present invention relates to a mobile station system in which a
mobile station apparatus measures reception quality of a signal
received from a base station apparatus to transmit reception
quality information to the base station apparatuses, and relates to
a base station apparatus and a mobile station apparatus which are
applied to such a mobile communication system.
BACKGROUND ART
In recent years, in mobile communication systems, there is
increased demand of data communication and there are proposed
various technologies in which high spectrum efficiency responding
to an increase of transmission data following the increased demand.
As one of technologies for enhancing the spectrum efficiency, there
is OFDMA (Orthogonal Frequency Division Multiple Access). This
OFDMA relates to a technology of modulation method in performing
communication by using the same frequency at all cells within
communication area composed of cells and can realize high speed
data communication.
In scheduling of transmission packets in the OFDMA system, there is
known a method in which mobile station apparatuses transmit, to the
base station apparatus, CQI (Channel Quality Indicator) which is
information indicating reception quality of a downlink state for
subcarriers in wideband, and the base station apparatus performs
scheduling of the packet on the basis of the CQI of subcarriers in
wideband transmitted from the each mobile station apparatuses.
Moreover, in scheduling of transmission packets in an OFDM
(Orthogonal Frequency Division Multiplexing) system using plural
subcarriers, there is also known a technology in which mobile
station apparatuses evaluate each channel states of a downlink
(frequency characteristics, i.e., characteristics of transmission
loss, etc., depending on frequency) and transmit information
obtained by quantizing each channel states to the base station
apparatus, and the base station apparatus determines subcarriers
assigned to each mobile station apparatuses on the basis of the
transmitted information (Patent Literature 1).
FIG. 18 is a view for illustrating a conventional communication
method between the base station apparatus and the mobile station
apparatus. Having received downlink information of the downlink
used for reception quality measurement from the base station
apparatus, the mobile station apparatus measures the reception
quality of each channel on the basis of the downlink information to
create a channel profile of propagation path.
The channel profile the mobile station apparatus has created is
transmitted from the mobile station apparatus to the base station
apparatus as reception quality information using an uplink. The
base station apparatus performs processing of adaptive modulation
and coding or frequency selective scheduling on a signal to be
transmitted from the base station apparatus to the mobile station
apparatus on the base of the reception quality information.
In regard to transmission of the reception quality information to
the base station apparatus by the mobile station apparatus, in
evolution of the third-generation radio access (Evolved Universal
Terrestrial Radio Access) being studied by the 3GPP (3rd Generation
Partnership Project) which is the International Standardization
Project, it is studied that the reception quality information is
transmitted from the mobile station apparatus to the base station
apparatus using a dedicated uplink control channel (hereinafter
referred to as PUCCH (Physical Uplink Control Channel), or an
uplink data channel (hereinafter refereed to as PUSCH (Physical
Uplink Shared Channel).
For example, in the non Patent Literature 1, there is proposed a
method to transmit, in transmitting the reception quality
information from the mobile station apparatus to the base station
apparatus, the reception quality information using the PUCCH or the
PUSCH depending on a kind of services different in required the
reception quality information. Patent Literature 1: Japanese Patent
Application Laid Open No. 2005-130491 Non-Patent literature 1: "CQI
handling during DRX", 3GPP, TSG RAN WG2 Meeting #58, R2-071901, May
2007
DISCLOSURE OF THE INVENTION
Problems to be Solved by the Invention
However, in the prior arts, there are no practical description of
what kind of control information the base station apparatus use to
control the mobile station apparatus in transmitting, on the PUCCH
or the PUSCH, the reception quality information from the mobile
station apparatus to the base station apparatus, and what kind of
information exchange between the base station apparatus and the
mobile station apparatus so that the reception quality information
is transmitted.
In transmission of the reception quality information, for example,
there are instances where the base station apparatus needs to
transmit, to the mobile station apparatus, a large information
amount such as the reception quality information with respect to
all channels obtained by dividing a transmission frequency band
every predetermined regions in order to perform suitable frequency
selective scheduling.
On the other hand, for example, there are also cases where the base
station apparatus requires the mobile station apparatus to transmit
the reception quality information of small information amount such
as average value of wideband in order to perform adaptive
modulation and coding, and the size of information amount of the
reception quality information to be transmitted from the mobile
station apparatus to the base station apparatus has a wide
range.
In addition, there is a demand such that the base station apparatus
controls the size and the transmission frequency of the reception
quality information. The base station apparatus should control the
size and the transmission frequency of the transmitted reception
quality information in consideration of an uplink resource within a
cell the base station apparatus itself controls. If large-sized
reception quality information is transmitted at high frequency
based on the decision of each mobile station apparatus, the uplink
resource within the cell runs out.
On the other hand, if small-sized reception quality information is
transmitted at low frequency, the uplink resource will be
wastefully used.
Namely, in transmission of the reception quality information from
the mobile station apparatus to the base station apparatus, it is
very important to control the mobile station apparatus using what
kind of control information from the base station apparatus, and to
transmit the reception quality information by performing what kind
of information exchange between the base station apparatus and the
mobile station apparatus, and it is required to employ an efficient
transmission control method in consideration of the information
amount and the transmission frequency of the reception quality
information to be transmitted.
The present invention is made in view of such circumstances, and
its object is to provide a mobile communication system, a base
station apparatus and a mobile station apparatus which can realize
the efficient transmission control of the reception quality
information which can flexibly treat the information amount and the
transmission frequency of the reception quality information.

BEST MODE FOR CARRYING OUT THE INVENTION
(First Embodiment)
First of all, a mobile communication system according to a first
embodiment of the present invention will be described. This mobile
communication system is composed of a base station apparatus and
mobile station apparatuses. FIG. 1 is a block diagram showing a
schematic configuration of the base station apparatus according to
the first embodiment of the present invention. A base station
apparatus 100 comprises a data control unit 101, a modulation
encoding unit 102, a mapping unit 103, an Inverse Fast Fourier
Transform (IFFT) unit 104, a radio transmission unit 105, radio
reception unit 106, a Fast Fourier Transform (FFT) unit 107, a
demodulation decoding unit 108, a data extracting unit 109, a
scheduler unit 110, a transmission information control unit 111 and
an antenna 112. The transmission information control unit 111
includes a modulation and coding control unit 111a, and a frequency
selective scheduler unit 111b.
In the base station apparatus 100, the data control unit 101
receives transmission data and control data which are transmitted
to the each mobile station apparatuses and sequentially transmits
respective data to the mobile station apparatuses according to
instruction from the scheduler unit 110. The modulation encoding
unit 102 performs modulation processing and error correction coding
processing on a signal output from the data control unit 101 on the
basis of modulation scheme and coding rate determined by the
modulation code control unit 111a to output the respective data to
the mapping unit 103. The mapping unit 103 performs mapping of data
output from the modulation encoding unit 102 onto respective
subcarriers on the basis of frequency selective scheduling
information output from the frequency selective scheduler unit 111b
to output the mapped data to the Inverse Fast Fourier Transform
unit 104.
The Inverse Fast Fourier Transform unit 104 performs processing of
Inverse Fast Fourier Transform on data output from the mapping unit
103, converts the data thus processed into a base band digital
signal of time series to output the digital signal thus provided,
and outputs the converted data to the radio transmission unit 105.
A signal output from the Inverse Fast Fourier Transform unit 104 is
subjected to digital analog conversion at the radio transmission
unit 105, up-converted into a signal having frequency suitable for
transmission, and then transmitted to the respective mobile station
apparatuses through the antenna 112.
The scheduler unit 110 performs scheduling of downlink and
scheduling of uplink on the basis of control information that each
mobile station apparatuses can use, such as resource region,
intermittent transmitting/receiving cycle, transmission data
channel format and buffer state. The modulation and coding control
unit 111a determines modulation scheme and coding rate to be
applied to respective data on the basis of reception quality
information transmitted from the mobile station apparatus to output
them to the modulation encoding unit 102. The frequency selective
scheduler unit 111b performs processing of frequency selective
scheduling to be applied to respective data on the basis of
reception quality information transmitted from the mobile station
apparatus to output the result to the mapping unit 103.
FIG. 2 is a block diagram showing a schematic configuration of the
mobile station apparatus of the first embodiment of present
invention. A mobile station apparatus 200 comprises, a data control
unit 201, a modulation encoding unit 202, a mapping unit 203, an
Inverse Fast Fourier Transform (IFFT) unit 204, a radio
transmission unit 205, a radio reception unit 206, a Fast Fourier
Transform (FFT) unit 207, a demodulation decoding unit 208, a data
extracting unit 209, a reception quality information control unit
210, and an antenna 211. The reception quality information control
unit 210 includes a reception quality information generating unit
210a, and a reception quality measurement unit 210b.
In the mobile station apparatus 200, the data control unit 201
receives transmission data and control data to be transmitted to
the base station apparatus, and sequentially transmits respective
data to the base station apparatus. The modulation encoding unit
202 performs modulation processing and error correction coding
processing on a signal output from the data control unit 201 to
output respective data to the mapping unit 203. The mapping unit
203 performs mapping of data output from the modulation encoding
unit 202 onto the respective sub carriers to output the mapped data
to the Inverse Fast Fourier Transform unit 204.
The Inverse Fast Fourier Transform unit 204 performs processing of
Inverse Fast Fourier Transform on a symbol sequence output from the
mapping unit 203 to convert it into a time-series baseband digital
signal, and outputs thus converted signal to the radio transmission
unit 205. The output signal from the Inverse Fast Fourier Transform
unit 204 is subjected to digital analog conversion at the radio
transmission unit 205 and up-converted into a signal having a
frequency suitable for transmission. Thereafter, the signal thus
obtained is transmitted to the base station apparatus through the
antenna 211.
The reception quality measurement unit 210b measures reception
quality of a signal received from the base station apparatus. The
reception quality information generating unit 210a generates
reception quality information transmitted to the base station
apparatus on the basis of information measured by the reception
quality measurement unit 210b.
FIG. 3 is a view showing a control signal transmitted from the base
station apparatus to the mobile station apparatus, and the
reception quality information, the uplink data which are
transmitted from the mobile station apparatus to the base station
apparatus, and the reception quality information transmission form.
FIG. 3 shows, as an example, the operation from #slot1 to #slot24.
The mobile station apparatus transmits data using PUSCH according
to resource assignment indicated by a downlink control channel
(referred to as PDCCH (Physical Downlink Control Channel)) from the
base station apparatus. Namely, this downlink control channel PDCCH
is a signal for permitting data transmission in the uplink
(hereinafter referred to as "L1/L2 grant" meaning uplink data
transmission permission signal).
The operation of the base station apparatus and the mobile station
apparatus at #slot2 in FIG. 3 will be described. The base station
apparatus which has determined to instruct the mobile station
apparatus to transmit the reception quality information transmits
the L1/L2 grant (uplink data transmission permission signal) which
includes simultaneous transmission permission information for
giving an instruction to simultaneously transmit the uplink data
and the reception quality information. The mobile station apparatus
having received the L1/L2 grant including the simultaneous
transmission permission information simultaneously transmits, to
the base station apparatus, the uplink data and the reception
quality information as indicated by slanting line attached
rectangular shape of FIG. 3. It is shown that at #slot2, from the
base station apparatus, the L1/L2 grant including the simultaneous
transmission permission information is transmitted using the PDCCH
at a timing for controlling #slot2 to the mobile station apparatus,
and the mobile station apparatus having received the signal
simultaneously transmits, to the base station apparatus, the uplink
data and the reception quality information.
Further, at #slot3, from the base station apparatus, the L1/L2
grant which does not include the simultaneous transmission
permission information is transmitted to the mobile station
apparatus, and the mobile station apparatus having received the
signal transmits, to the base station apparatus, the uplink data
using the PUSCH in a physical format which does not include the
reception quality information, as indicated by a white rectangle.
FIG. 3 similarly shows that the L1/L2 grant which includes the
simultaneous transmission permission information is transmitted
from the base station apparatus at #slot9 and #slot20, and the
mobile station apparatus having received the signal simultaneously
transmits the uplink data and the reception quality
information.
FIG. 4 is a view showing transmission form when the mobile station
apparatus simultaneously transmits the uplink data and the
reception quality information. FIG. 4 shows, as an example, two
physical formats (transmission form 1 and transmission form 2).
Data transmitted from the mobile station apparatus to the base
station apparatus is represented by 14 OFDM symbols, and there are
arranged, in these 14 OFDM symbols, known reference symbols (pilot
signal which will be refereed to as RS hereinafter) used for
propagation path estimation for performing data demodulation and
the reception quality information and the uplink data having the
numbers different from each other in the transmission forms 1 and
the transmission form 2.
In the transmission form 1, there are arranged the reception
quality information at the 2nd, 6-th, 9-th, and 13-th OFDM symbols
and the uplink data at 3-rd, 4-th, 7-th, 10-th, 11-th and 14-th
OFDM symbols. In the transmission form 2, there are arranged the
reception quality information at 2nd, 4-th, 6-th, 9-th, 11-th and
13-th OFDM symbols and the uplink data at 3-rd, 7-th, 10-th and
14-th OFDM symbols.
The L1/L2 grant including the simultaneous transmission permission
information is transmitted from the base station apparatus. The
mobile station apparatus having received the signal simultaneously
transmits, to the base station apparatus, the uplink data and the
reception quality information in transmission form as indicated by
the transmission form 1 or the transmission form 2.
The base station apparatus can specify by a RRC signaling (radio
resource control signal) the physical format of the uplink data and
the reception quality information the mobile station apparatus
simultaneously transmits. For example, the base station apparatus
sets ratio of the uplink data and the reception quality information
for each OFDM symbol unit, and makes a setting in detail of the
transmission form 1 or the transmission form 2 etc. For example,
for transmission data of 14 OFDM symbols, there may be employed an
approach to transmit information that the reception quality
information is included in 4 OFDM symbols, or information that the
uplink data is included in 6 OFDM symbols. Further, there may be
employed an approach to simply notify transmission form selected
from transmission forms determined in advance. In addition, there
may be employed an approach to specify, in advance by the RRC
signaling, a modulation scheme and a coding scheme for coding the
reception quality information.
Further, arrangement of the RS, the uplink data and the reception
quality information is changed in the time axis direction (14 OFDM)
between the transmission forms 1 and the transmission forms 2 in
FIG. 4, but such arrangement may be changed with respect to the
frequency axis direction. In addition such arrangement may be
automatically changed depending on the size of resource of PUSCH
assigned by the L1/L2 grant. For example, only the resource unit
(minimum unit of time frequency block of PUSCH) arranged in a low
frequency band can transmit the reception quality information, and
the resource unit arranged in the remaining high frequency band can
transmit only the uplink data. Also a modulation scheme and a
coding scheme for coding the reception quality information may be
changed according to a modulation scheme and a coding scheme of
PUSCH specified by the L1/L2 grant.
The mobile station apparatus stores the physical format specified
by the RRC signaling from the base station apparatus. In case that
the L1/L2 grant including the simultaneous transmission permission
signal is transmitted from the base station apparatus, the mobile
station apparatus simultaneously transmits the uplink data and the
reception quality information in the physical format (e.g., format
such that 4 OFDM symbols are used for the reception quality
information and 6 OFDM symbols are used for the uplink data as
indicated by the transmission form 1 in FIG. 4).
Here, there may be employed as information included in the RRC
signaling with respect to the physical format for simultaneous
transmission, any information such that the mobile station
apparatus determines the ratio in simultaneously transmitting the
uplink data and the reception quality information, such as, for
example index given to plural kinds of physical format determined
in advance, the number of OFDM symbols in which the uplink data is
included (e.g., 6 OFDM for the uplink data in 14 OFDM), or the
number of OFDM symbols in which the reception quality information
is included (e.g., 4 OFDM for the reception quality information in
14 OFDM) etc.
Further, while two kinds of forms as shown in FIG. 4 as described
as an example of transmission form, there may be employed any
arrangement other than the above as arrangement of the RS, the
uplink data and the reception quality information. In addition,
there may be included information, e.g., ACK/NACK signal other than
the RS, the uplink data and the reception quality information
within OFDM signal to be transmitted.
FIG. 5 is a view showing content and form to be transmitted in the
slot in the first embodiment according to the present invention.
FIG. 6 is a sequence chart showing the operation of the first
embodiment according to the present invention. In this example, for
clarifying, there are shown slots and the sequence corresponding to
#slot1 to #slot12 in FIG. 3. In addition, the uplink may be
referred to as "uplink" and the downlink may be referred to as
"downlink" hereinafter.
In FIG. 5 and FIG. 6, at #slot2, the base station apparatus
transmits, to the mobile station apparatus, the L1/L2 grant
including the simultaneous transmission permission information
(step S1). The mobile station apparatus having received the signal
simultaneously transmits, to the base station apparatus, the uplink
data and the reception quality information (step S2). Also at
#slot9, similar processing is performed (step S7, S8). At #slot3,
the base station apparatus transmits, to the mobile station
apparatus, the L1/L2 grant which does not include the simultaneous
transmission permission information (step S3). The mobile station
apparatus having received the signal transmits the uplink data in
the physical format which does not include the reception quality
information (step S4). Also at #slot4, #slot11, and #slot12,
similar processing is performed (steps S5, S6, S9, S10, S11 and
S12).
FIG. 7 is a view showing content and form to be transmitted in the
slot when the physical format for simultaneous transmission is
specified by the RRC signaling from the base station apparatus to
the mobile station apparatus in the first embodiment of the present
invention. Moreover, FIG. 8 is a sequence chart showing the
operation when the physical format for simultaneous transmission is
specified by the RRC signaling from the base station apparatus to
the mobile station apparatus in the first embodiment of the present
invention. The embodiment shown in FIG. 7 and FIG. 8 differs from
the case shown in FIGS. 5 and 6 in that the RRC signaling for
specifying the physical format for simultaneous transmission is
transmitted from the base station apparatus to the mobile station
apparatus at #slot1 and #slot8.
In FIG. 7 and FIG. 8, at #slot1, the base station apparatus
transmits, to the mobile station apparatus, the RRC signaling for
specifying the physical format for simultaneous transmission (step
S21). In this example, it is assumed that the transmission form 1
in FIG. 4 is specified by the RRC signaling. The mobile station
apparatus stores the physical format for simultaneous transmission
(the transmission form 1). At #slot2, the base station apparatus
transmits, to the mobile station apparatus, the L1/L2 grant
including the simultaneous transmission permission signal (step
S22). The mobile station apparatus having received the signal
transmits, to the base station apparatus, the uplink data and the
reception quality information in the stored transmission form 1
(step S23).
Next, the base station apparatus transmits, to the mobile station
apparatus, the L1/L2 grant which does not include the simultaneous
transmission permission signal at #slot3 (step 24). The mobile
station apparatus transmits, to the base station apparatus, the
uplink data (step S25). Also at #slot4, #slot6, #slot11 and
#slot12, similar processing is performed (step S26, S27, S28, S29
and S33 to S36). At #slot 8, the base station apparatus transmits,
to the mobile station apparatus, the RRC signaling including
specification of the physical format for simultaneous transmission
(step S30). Here, it is assumed that the transform form 2 in FIG. 4
is specified by the RRC signaling. The mobile station apparatus
stores the physical format for simultaneous transmission (the
transmission form 2). At #slot9, the base station apparatus
transmits, to the mobile station apparatus, the L1/L2 grant
including the simultaneous transmission permission signal (step
S31). The mobile station apparatus having received the signal
transmits, to the base station apparatus, the uplink data and the
reception quality information in the stored transmission form 2
(step S32).
As described above, according to the first embodiment of the
present invention, the base station apparatus transmits the L1/L2
grant including the simultaneous transmission permission
information for permitting simultaneous transmission of the uplink
data and the reception quality information, the mobile station
apparatus having received the signal simultaneously transmits the
uplink data and the reception quality information, and whereby the
base station apparatus can control the transmission frequency of
the reception quality information, thus making it possible to
perform the transmission control of the reception quality
information in consideration of the uplink resource within the
cell.
Moreover, since the uplink data and the reception quality
information can be simultaneously transmitted, it is possible to
reduce wasteful use of the resource of the L1/L2 grant. Namely,
when a transmission instruction of the reception quality
information is given at a fixed timing using the radio resource
control signal (RRC signaling) from the base station apparatus to
the mobile station apparatus, if there is a need to give a
transmission instruction of the reception quality information
dynamically using the uplink data transmission permission signal,
it is required to give an instruction at which timing the reception
quality information is to be transmitted, using the uplink data
transmission permission signal from the base station apparatus to
the mobile station apparatus. According to the present invention,
since the uplink data transmission permission signal including the
simultaneous transmission permission information for instructing
the mobile station apparatus to simultaneously transmit the
reception quality information and the uplink data is transmitted to
the mobile station apparatus, wasteful use of the resource of the
uplink data transmission permission signal is reduced in the
downlink, and thereby the resource can be effectively utilized.
Further, the base station apparatus transmits the RRC signaling for
specifying the physical format for simultaneous transmission in
simultaneous transmitting the uplink data and the reception quality
information, and thereby the transmission control to flexibly treat
the information amount of the reception quality information
transmitted from the mobile station apparatus can be performed.
(Second Embodiment)
FIG. 9 is a view showing a control signal transmitted from the base
station apparatus to the mobile station apparatus, and the
reception quality information, the uplink data which are
transmitted from the mobile station apparatus to the base station
apparatus, and the reception quality information transmission form
in the second embodiment according to the present invention. FIG. 9
shows, as an example, the operation from #slot1 to #slot24.
First, the base station apparatus transmits the RRC signaling which
includes resource assignment and transmission interval when the
mobile station apparatus transmits the reception quality
information using the PUCCH. In general, since the resource region
assigned as the PUCCH is smaller than the resource region assigned
as the PUSCH, the size of information amount to be transmitted
becomes small. Namely, the reception quality information the mobile
station apparatus transmits using the PUCCH is the reception
quality information having small information amount, and the
reception quality information the mobile station apparatus
transmits using the PUSCH is the reception quality information
having large information amount.
The operation at #slot2 will now be described. The mobile station
apparatus in which the resource assignment and the transmission
interval in transmitting the reception quality information using
the PUCCH are set by the RRC signaling from the base station
apparatus, transmits, to the base station apparatus, the reception
quality information of small information amount in the set resource
of the PUCCH and at the set transmission interval. FIG. 9 shows,
the mobile station apparatus transmits the reception quality
information using the PUCCH at the transmission interval of five
slots.
Next, the operation at #slot3 will be described. At the #slot3, as
described in the first embodiment, the base station apparatus
transmits, to the mobile station apparatus, the L1/L2 grant
including the simultaneous transmission permission information for
instructing the mobile station apparatus to simultaneously transmit
the uplink data and the reception quality information. The mobile
station apparatus having received the L1/L2 grant including the
simultaneous transmission permission information from the base
station apparatus simultaneously transmits the uplink data and the
reception quality information of large information amount using the
PUSCH. The transmission form of data transmitted at this time may
be controlled by the RRC signaling including the physical format
for simultaneous transmission from the base station apparatus
similarly to that shown in the first embodiment.
The operation of #slot7 will now be described. The #slot7 indicates
the case where at a slot in which is set so as to transmit the
reception quality information using the PUCCH in advance, further
the base station apparatus transmits the L1/L2 grant including the
simultaneous transmission permission information. At #slot7, the
mobile station apparatus having received the L1/L2 grant including
the simultaneous transmission permission information from the base
station apparatus simultaneously transmits, to the base station
apparatus, the uplink data and the reception quality information
using the PUSCH.
Here, as the reception quality information transmitted
simultaneously with the uplink data, there can be transmitted the
reception quality information of large information amount, or the
reception quality information of small information amount
attempting to be transmitted on PUCCH and the reception quality
information of large information amount, or the reception quality
information of small information amount attempting to be
transmitted on PUCCH and the relationship thereof. The reception
quality information having small information amount and the
relationship thereof indicates the reception quality information
having small information amount attempting to be transmitted on
PUCCH and difference information with respect to the reception
quality information, etc.
Specifically, it indicates that with the average value of wideband
reception quality information as the reception quality information
of small information amount, narrow band reception quality
information is expressed as the difference information from the
average value thereof and is transmitted. For example, in case that
there is a desire to transmit four values of 15, 12, 10 and 8 as
the reception quality information, the average value as small
information amount is determined to be "9". Moreover, the
difference information from the average value as "the relationship
thereof" is determined to be 6, 3, 1 and -1. This information is
transmitted simultaneously with the uplink data on PUSCH. As stated
above, since the difference information of the average value can be
expressed by lesser number of bits, it is possible to reduce the
number of bits of the reception quality information transmitted on
the uplink data channel.
Further, the operation of the base station apparatus at #slot7 will
be described. When the mobile station apparatus transmits, to the
base station apparatus, the reception quality information of small
information amount attempting to be transmitted on PUCCH and the
reception quality information of large information amount, or the
reception quality information of information amount attempting to
be transmitted on PUCCH and the relationship thereof, the resource
of the PUCCH which has been set by the RRC signaling in advance
does not transmit any information.
The base station apparatus transmits the L1/L2 grant including the
simultaneous transmission permission information to thereby
recognize in advance that there is no information to be transmitted
in the resource of the PUCCH. For this reason, other mobile station
apparatus are performed scheduling using the resource so as to
transmit information of the uplink (e.g., ACK/NACK signal).
By performing such scheduling, it is possible to use, with respect
to other mobile station apparatus, the resource of the PUCCH which
has been maintained in advance for transmitting the reception
quality information, thus making it possible to more efficiently
use the uplink resource.
At #slot12, there is shown the case where at a slot which the base
station apparatus set by the RRC signaling for the mobile station
apparatus so as to transmit the reception quality information
having small information amount using the PUCCH, the base station
apparatus transmits the L1/L2 grant which does not include the
simultaneous transmission permission information. The operation at
the #slot12 will be described. At the #slot12, the mobile station
apparatus having received the L1/L2 grant which does not include
the simultaneous transmission permission information from the base
station apparatus simultaneously transmits, using the PUSCH, the
uplink data and the reception quality information of small
information attempting to be transmitted on the PUCCH.
At this time, as the physical format for simultaneously
transmitting the uplink data and the reception quality information
of small information attempting to be transmitted on the PUCCH to
be transmitted using the PUSCH, a format determined in advance is
used, or such format is controlled by the RRC signaling. Namely,
there are defined the physical format for simultaneously
transmitting the reception quality information of small information
attempting to be transmitted on PUCCH and the uplink data, and the
physical format for simultaneously transmitting the reception
quality information of large information and the uplink data in
case that receiving the L1/L2 grant including the simultaneous
transmission permission information.
Also at #slot12, the base station apparatus transmits the L1/L2
grant which does not include the simultaneous transmission
permission information to thereby in advance recognized that there
is no information to be transmitted in the resource of the PUCCH,
other mobile station apparatus are performed scheduling so as to
transmit the uplink information, (e.g., ACK/NACK signal) using the
resource.
FIG. 10 is a view showing content and form to be transmitted in the
slot in the second embodiment according to the present invention.
Moreover, FIG. 11 is a sequence chart showing the operation of the
second embodiment according to the present invention. Here, for
facilitation of explanation, there are shown slots and the sequence
corresponding to #slot1 to #slot12 in FIG. 9. In FIG. 10 and FIG.
11, at #slot1, the resource assignment and the transmission
interval when the mobile station apparatus transmits the reception
quality information using the PUCCH are set by the RRC signaling
from the base station apparatus. At #slot2, the mobile station
apparatus transmits the reception quality information of small
information amount in the set recourse of the PUCCH and at the set
transmission interval (step S41). At #slot3, the base station
apparatus transmits the L1/L2 grant including the simultaneous
transmission permission information (step S42). The mobile station
apparatus having received the signal simultaneously transmits,
using the PUSCH, the uplink data and the reception quality
information of large information amount (step S43).
At #slot4, the base station apparatus transmits the L1/L2 grant
which does not include the simultaneous transmission permission
information (step S44). The mobile station apparatus having
received the signal transmits, using the PUSCH, the uplink data
(step S45). Also at #slots 8 and 10, similar processing is
performed (steps S48 to S51).
At #slot7, the base station apparatus transmits the L1/L2 grant
including the simultaneous transmission permission information
(step S46). The mobile station apparatus having received the signal
transmits, using the PUSCH, the uplink data and the reception
quality information of large information amount, or the uplink data
and the reception quality information of small information amount
attempting to be transmitted on PUCCH and the reception quality
information of large information amount, or the uplink data and the
reception quality information of small information amount
attempting to be transmitted on PUCCH and the relationship thereof
(step S47). In addition, the base station apparatus performs
scheduling so that other mobile station apparatus can transmit the
uplink information using such resource.
At #slot12, the base station apparatus transmits the L1/L2 grant
which does not include the simultaneous transmission permission
information (step S52). The mobile station apparatus having
received the signal transmits, using the PUSCH, the uplink data and
the reception quality information attempting to be transmitted on
PUCCH (step S53). In addition, the base station apparatus performs
scheduling so that other mobile station apparatus can transmit the
uplink information using such resource.
As stated above, according to the second embodiment of the present
invention, the base station apparatus transmits the RRC signaling
including the resource and the transmission interval for
transmitting the reception quality information using the PUCCH, and
transmits the L1/L2 grant including the simultaneous transmission
permission information for permitting simultaneous transmission of
the uplink data and the reception quality information, thereby
enabling control of the transmission frequency of the reception
quality information and the transmission control to flexibly treat
the information amount of the reception quality information.
Moreover, since the uplink data and the reception quality
information can be simultaneously transmitted, it is possible to
reduce wasteful use of the resource of the L1/L2 grant. Namely,
when a transmission instruction of the reception quality
information is given at a fixed timing using the radio resource
control signal (RRC signaling) from the base station apparatus to
the mobile station apparatus, if there is a need to give a
transmission instruction of the reception quality information
dynamically using the uplink data transmission permission signal,
it is required to give an instruction at which timing the reception
quality information is to be transmitted, using the uplink data
transmission permission signal from the base station apparatus to
the mobile station apparatus. According to the present invention,
since the uplink data transmission permission signal including the
simultaneous transmission permission information for instructing
the mobile station apparatus to simultaneously transmit the
reception quality information and the uplink data is transmitted to
the mobile station apparatus, wasteful use of the resource of the
uplink data transmission permission signal is reduced in the
downlink, and thereby the resource can be effectively utilized.
(Third Embodiment)
FIG. 12 is a view showing a control signal transmitted from the
base station apparatus to the mobile station apparatus, and the
reception quality information, the uplink data which are
transmitted from the mobile station apparatus to the base station
apparatus, and the reception quality information transmission form.
FIG. 12 shows, as an example, the operation from #slot1 to #slot24.
First, the base station apparatus transmits, to the mobile station
apparatus, the RRC signaling including a reception quality
information transmittable time region. This reception quality
information transmittable time region is a region where the mobile
station apparatus having received the L1/L2 grant at any slot
within the region can simultaneously transmit the uplink data and
the reception quality information. Thus, there is no necessity to
include simultaneous transmission permission information in the
L1/L2 grant to be transmitted from the base station apparatus, thus
making it possible to more efficiently use downlink resource.
FIG. 12 shows that the reception quality information transmittable
time regions are set with respect to slots of #slot1 to #slot4,
#slot11 to #slot14 and #slot21 to #slot24 by the RRC signaling from
the base station apparatus. Moreover, it shows that the mobile
station apparatus simultaneously transmits the uplink data and the
reception quality information with respect to the L1/L2 grant
(#slot2, #slot11 and #slot23) first received within the reception
quality information transmittable time region.
The transmission form when the mobile station apparatus
simultaneously transmits the uplink data and the reception quality
information is similar to that shown in the first embodiment, and
the RRC signaling including the physical format for simultaneous
transmission may be transmitted from the base station
apparatus.
FIG. 13 is a view showing content and form to be transmitted in the
slot in the third embodiment according to the present invention.
Moreover, FIG. 14 is a sequence chart showing the operation of the
third embodiment according to the present invention. Here, for
facilitation of explanation, there are shown slots and the sequence
corresponding to #slot1 to #slot12 in FIG. 12.
In FIG. 13 and FIG. 14, at #slot1, the base station apparatus
transmits, to the mobile station apparatus, the RRC signaling
including the reception quality information transmittable time
region (step S60). The mobile station apparatus having received an
L1/L2 grant at any slot within the time region (step S61)
simultaneously transmits the uplink data and the reception quality
information (step S62). Also at #slot11, similar processing is
performed (steps S69, S70). At #slot3, the mobile station apparatus
having received the L1/L2 grant (step S63) transmits the uplink
data (step S64).
In this example, since it shows that the uplink data and the
reception quality information are simultaneously transmitted with
respect to the L1/L2 grant first received with the reception
quality information transmittable time region, simultaneous
transmission is not performed at #slot3. Also at #slot6, #slot7 and
#slot12, similar processing is performed (steps S65 to S68, S71 and
S72).
In the third embodiment of the present invention, for facilitation
of explanation description has been given in connection with the
example where the uplink data and the reception quality information
are simultaneously transmitted with respect to the L1/L2 grant
first received within the reception quality information
transmittable time region. However, the reception quality
information may be transmitted at any slot within the reception
quality information transmittable time region.
As described above, according to the third embodiment of the
present invention, the base station apparatus transmits, to the
mobile station apparatus, the RRC signaling that includes the
reception quality information transmittable time region, and the
mobile station apparatus having received the L1/L2 grant within the
time region simultaneously transmits the uplink data and the
reception quality information. Thus, the base station apparatus can
control the transmission frequency of the reception quality
information and can perform the transmission control which flexibly
treats the information amount of the reception quality information.
Further, the uplink data and the reception quality information can
be simultaneously transmitted, which leads to reduction in wasteful
use of the resource of the L1/L2 grant.
Moreover, it is possible to perform, more efficiently, the
transmission control of the reception quality information without
adding information to the L1/L2 grant to be transmitted from the
base station apparatus to the mobile station apparatus. Namely,
when a transmission instruction of the reception quality
information is given at fixed timing using the radio resource
control signal (RRC signaling) from the base station apparatus to
the mobile station apparatus, if there is a need to give a
transmission instruction of the reception quality information
dynamically using the uplink data transmission permission signal,
it is required to give an instruction at which timing the reception
quality information is to be transmitted, using the uplink data
transmission permission signal from the base station apparatus to
the mobile station apparatus. According to the present invention,
since the uplink data transmission permission signal including the
simultaneous transmission permission information for instructing
the mobile station apparatus to simultaneously transmit the
reception quality information and the uplink data is transmitted to
the mobile station apparatus, wasteful use of the resource of the
uplink data transmission permission signal is reduced, and thereby
the resource can be effectively utilized.
(Fourth Embodiment)
FIG. 15 is a view showing a control signal transmitted from the
base station apparatus to the mobile station apparatus, and the
reception quality information, the uplink data which are
transmitted from the mobile station apparatus to the base station
apparatus, and reception quality information transmission form in
the fourth embodiment of the present invention. In FIG. 15, as an
example, there is shown an operation from #slot1 to #slot24. First,
the base station apparatus transmits, to the mobile station
apparatus, the RRC signaling which includes the resource assignment
and the transmission interval when the mobile station apparatus
transmits the reception quality information using the PUCCH, and
the reception quality information transmittable time region.
In FIG. 15, it shows that the reception quality information is
transmitted using the PUCCH at the transmission interval of five
slots, and to set reception quality information transmittable time
region at #slot1 to #slot4, #slot11 to #slot14 and #slot21 to
#slot24. Moreover, it shows that the mobile station apparatus
simultaneously transmits the uplink data and the reception quality
information with respect to the L1/L2 grant (#slot3, #slot12, and
#slot23) first received within the reception quality information
transmittable time region.
At #slot2, the mobile station apparatus in which the resource
assignment and the transmission interval in transmitting the
reception quality information using the PUCCH are set by the RRC
signaling from the base station apparatus transmits, using the
PUCCH, the reception quality information of small information
amount in the resource of the PUCCH and at the transmission
interval determined at that setting.
At #slot3, the mobile station apparatus having received the L1/L2
grant from the base station apparatus simultaneously transmits the
uplink data and the reception quality information. While the
transmission form in simultaneously transmitting the uplink data
and the reception quality information is similar to that shown in
the first embodiment, the RRC signaling including the physical
format for simultaneous transmission may be transmitted from the
base station apparatus.
At #slot7, it is shown that the base station apparatus has
transmitted the L1/L2 grant at a slot which is set so as to
transmit the reception quality information of small information
amount using the PUCCH. At the #slot7, the mobile station apparatus
having received the L1/L2 grant from the base station apparatus
simultaneously transmits, using the PUSCH, the uplink data and the
reception quality information of small information attempting to be
transmitted on PUCCH. At this time, as described in the second
embodiment, the base station apparatus transmits the L1/L2 grant to
thereby recognize in advance that there is no information to be
transmitted by the resource of the PUCCH, other mobile station
apparatus are performed scheduling so as to transmit the uplink
information (e.g., ACK/NACK signal) using the resource.
At #slot12, it is shown that the L1/L2 grant is transmitted within
the reception quality information transmittable time region at the
slot which is set so as to transmit the reception quality
information of small information amount using the PUCCH. At the
#slot12, the mobile station apparatus having received the L1/L2
grant from the base station apparatus simultaneously transmits,
using the PUSCH, the uplink data and the reception quality
information. Here, as the reception quality information transmitted
simultaneously with the uplink data, as described in the second
embodiment, it is possible to transmit the reception quality
information of large information amount, the reception quality
information of small information amount and the reception quality
information of large information amount attempting to be
transmitted on PUCCH, or the reception quality information of small
information amount attempting to be transmitted on PUCCH and the
relationship thereof.
FIG. 16 is a view showing content and form to be transmitted in the
slot in the fourth embodiment according to the present invention.
Moreover, FIG. 17 is a sequence chart showing the operation of the
fourth embodiment according to the present invention. Here, for
facilitation of explanation, there are shown slots and the sequence
corresponding to #slot1 to #slot12 in FIG. 15.
In FIG. 16 and FIG. 17, at #slot1, the base station apparatus
transmits the RRC signaling which includes the resource assignment
and the transmission interval in transmitting the reception quality
information using the PUCCH, and the reception quality information
transmittable time region (step S80). The mobile station apparatus
having received the signal transmits the reception quality
information of small information amount in the resource of the
PUCCH and at the transmission interval determined by the setting
(step S81). In addition, in the case of receiving the L1/L2 grant
at any slot within the reception quality information transmittable
time region (step S82), the uplink data and the reception quality
information are simultaneously transmitted (step S83).
At the #slot2, the mobile station apparatus transmits, using the
PUCCH, the reception quality information of small information
amount. At #slot3, the base station apparatus transmits the L1/L2
grant (step S82). The mobile station apparatus having received the
signal simultaneously transmits the uplink data and reception
quality information (step S83). At #slot4, the base station
apparatus transmits the L1/L2 grant (step S84). The mobile station
apparatus having received the signal transmits the uplink data
(step S85).
In this example, since it shows that the uplink data and the
reception quality information are transmitted simultaneously with
respect to the L1/L2 grant received first within the reception
quality information transmittable time region, simultaneous
transmission is not performed at #slot4. At #slot6 and #slot9
similar processing is performed (steps S86, S87, S90 and S91).
At #slot7, the base station apparatus transmits the L1/L2 grant
(step S88) and the mobile station apparatus having received the
signal transmits, using the PUSCH, the uplink data and the
reception quality information of small information amount
attempting to be transmitted on the PUCCH (step S89). In addition,
the base station apparatus performs scheduling so that other mobile
station apparatus can transmit the uplink information using such
resource.
At #slot 12, the base station apparatus transmits the L1/L2 grant
(step S92) and the mobile station apparatus having received the
signal transmits the uplink data and the reception quality
information having large information amount, or the uplink data and
the reception quality information of small information amount and
the reception quality information of large information amount
attempting to be transmitted on PUCCH, or the uplink data and the
reception quality information of small information amount
attempting to be transmitted on PUCCH and the relationship thereof
(step S93).
In the fourth embodiment, for facilitation of explanation,
description has been given in connection with the example to
simultaneously transmit the uplink data and the reception quality
information with respect to the L1/L2 grant first received within
the reception quality information transmittable time region.
However, the reception quality information can be transmitted at
any slot within the reception quality information transmittable
time region.
As described above, according to the fourth embodiment of the
present invention, the base station apparatus transmits, to the
mobile station apparatus, the RRC signaling including the resource
assignment, the transmission interval when the mobile station
apparatus transmits the reception quality information using the
PUCCH, and the reception quality information transmittable time
region. The mobile station apparatus having received the L1/L2
grant within the time region simultaneously transmits the uplink
data and the reception quality information so that the base station
apparatus can control the transmission frequency of the reception
quality information, and can perform the transmission control which
flexibly treats the information amount of the reception quality
information.
Further, the uplink data and the reception quality information can
be transmitted simultaneously, which leads to reduction of wasteful
use of the resource of the L1/L2 grant. Namely, when a transmission
instruction of the reception quality information is given at a
fixed timing using the radio resource control signal (RRC
signaling) from the base station apparatus to the mobile station
apparatus, if there is a need to give a transmission instruction of
the reception quality information dynamically using the uplink data
transmission permission signal, it is required to give an
instruction at which timing the reception quality information is to
be transmitted, using the uplink data transmission permission
signal from the base station apparatus to the mobile station
apparatus. According to the present invention, since the uplink
data transmission permission signal including the simultaneous

side. Moreover, since it is possible to properly use the uplink
control channel and the uplink data channel in transmitting the
reception quality information, it becomes possible to perform
transmission control which flexibly treats the information amount
of the reception quality information in the base station apparatus.
Further, since the reception quality information and the uplink
data are simultaneously transmitted to the base station apparatus
using the uplink data channel, the resource of the uplink control
channel at that time becomes empty. For this reason, the base
station apparatus can perform scheduling so that other mobile
station apparatus can use the resource of empty uplink control
channel. Thus, it becomes possible to more efficiently use the
uplink resource.
In addition, in the mobile station apparatus of this embodiment,
the reception unit receives, from the base station apparatus, the
radio resource control signal including information for specifying
the physical format in simultaneously transmitting the reception
quality information and the uplink data, and the transmission unit
simultaneously transmits, to the base station apparatus, the
reception quality information and the uplink data according to the
specified physical format.
As described above, the mobile station apparatus of the present
embodiment, receives the radio resource control signal including
information for specifying the physical format in simultaneously
transmitting the reception quality information and the uplink data
from the base station apparatus. Accordingly, it becomes possible
to control, on the base station apparatus side, the physical format
in simultaneously transmitting the reception quality information
and the uplink data.
